In fulfillment of a commission from the BBC for a work in commemoration of the 75th anniversary of the BBC Symphony Chorus, Mark-Anthony Turnage produced Calmo, an untypically quiet and gentle work for chorus with handbells – and, what has become something of a signature instrument for him, desk bells. The text of the work consists of the words ‘Dona nobis pacem’ and their translations in several languages. It is dedicated to the memory of Turnage's friend Sue Knussen. Calmo's intense eloquence was enhanced by its brevity, and, both despite and because of it, stood out in a program of music for chorus, harp, and organ by an assortment of older and newer Czech and British Composers, including Janáček, MacMillan, Holst, and Eben, presented by the BBC Symphony Chorus, conducted by Stephen Jackson.
